The sweet music sounded. Ye Han rubbed his half-asleep eyes, climbed up with his arms, rubbed his face to wake himself up, got out of bed in slow motion, spread his arms and stretched.
Sensing Ye Han's movement, the lights on the cabin roof automatically lit up, casting a soft light. Ye Han immediately looked at the bulkhead. The multi-functional detector embedded in the bulkhead displayed the real-time temperature in the cabin.
, humidity, pressure and air composition, and it was confirmed that all values were within the normal range, and I couldn't help but secretly breathed a sigh of relief.
Such multi-functional detectors can be seen everywhere in the functional cabin. Once there is an abnormality in the cabin environment, the environmental maintenance system will immediately sound a special alarm to remind the personnel in the cabin to pay attention.
This is the lunar surface far away from the earth. Any oversight may result in the destruction of the capsule and loss of life. Not to mention, the cost of sending astronauts to the moon is an astronomical figure. The loss of any one person will mean that
Billions of dollars have been wasted, and necessary safety measures must not be omitted.
Ye Han's bedroom is very small. After unfolding the single bed, there is only half a square meter of space to stay.
Just click on the bulkhead and the air extraction system will extract the air from the single bed to make more space.
Sitting on the half-shrunken bed, I reached out and opened the storage cabinet on the bulkhead. The downward-opening cabinet door turned into a small desk.
Ye Han took out his compact mobile phone from the cabinet, turned it on and immediately smiled. The signal was full!
Mobile phones are communication tools provided to astronauts. They can use the communication equipment of the temporary base on the moon to act as a transfer station to connect signals with the ground communication system, turning all astronauts' mobile phones into part of the earth's communication network.
To put it bluntly, with this special mobile phone, you can directly dial and make calls.
Because of the long distance, signal loss, signal interference and many other reasons, the sound quality of this thing is always unsatisfactory, and there is a delay of more than a second when speaking.
These are nothing, after all, it is very rare to be able to directly communicate with relatives and friends on the moon, but what makes all astronauts unbearable is that this thing must be used for a limited time!
It's not that the ground command center or other departments restrict astronauts from using mobile phones, but that the temporary lunar base is not only located at the poles of the moon, but also inside a pitiful crater, surrounded by mountains several kilometers high. The communication signals between the temporary base and the earth are blocked.
The crater blocks it, making it impossible to communicate directly with the Earth.
The solution to this problem is to release a moon-orbiting satellite when Kongtian-1 arrives at the moon. The orbiting period of this satellite is sixteen hours. Only when the satellite flies out of the crater and acts as a transfer station can the temporary base on the moon surface communicate with the ground.
Establish direct contact.
The time limit for each satellite appearance is about three hours. If you miss this period, you will have to wait for more than ten hours to re-establish contact with the ground.
Limited to the current conditions, the earth and moon can only tolerate intermittent communication environment. In order to solve this problem, Kongtian-2 will carry several satellites and release all satellites in sequence to form a communication network over the moon. At that time, it can communicate with the ground
Establish all-weather uninterrupted communication links and completely solve the problem of communication difficulties.
But now Ye Han still has to endure intermittent communication. He didn't dare to neglect, and quickly opened the phone. Bai Xiaoting appeared on the screen, showing a smile and saying: "Ye Han, are you okay? It's only been a few days.
I can’t stand thinking about you. When the base is built in the future, I will definitely be the first to apply..."
Bai Xiaoting talked a lot of useless nonsense, but Ye Han listened with great interest. It wasn't until the end of the video that she remembered to look at the time.
The video was sent out nine hours ago, around 9:00 pm ground time.
While the signal was not cut off, Ye Han quickly recorded a video and sent it back. He didn't mention the difficulties and only said good things.
Although Ye Han knew very well that Bai Xiaoting knew about the situation of the moon, he just made up such a self-deceptive statement and sent it back. Whether Bai Xiaoting believed it or not was not in Ye Han's consideration at all. It was nothing more than reporting good news, not bad news, even if Bai Xiaoting didn't believe it.
, how can she still run to the moon?
After putting down the phone, Ye Han opened the single-layer airtight door and left his small bedroom. He happened to meet Duan Zhiyang who lived next door.
The surface environment of the moon is harsh. It is not easy to build a temporary base here. The cost of sending various materials to the moon is an astronomical sum that ordinary people cannot even imagine. The living space in the temporary base is no longer usable.
An inch of land is worth a lot of money. Basically, every inch of land is worth a lot of money, or even an inch of land is worth a pound of gold.
In a place like this, it is the most frugal and economical arrangement for everyone to sleep in a collective dormitory.
However, due to the harsh environment on the lunar surface, once the living module malfunctions, it is likely to cause casualties to the personnel in the module. If everyone lives together, it will be wiped out in one fell swoop, which will be a devastating blow to the Moon Palace Project.
On the contrary, by separating everyone, even if the living cabin fails, casualties can be kept to a minimum.
Again, the cost of sending an astronaut to the moon is too high. Even with the strength of the country, it cannot afford such a loss.
As soon as the two met, they rushed to the bathroom in unison. Ye Han was near the waterfront and rushed in first, laughing proudly.
Duan Zhiyang bared his teeth helplessly: "Hurry up!"
"Got it!" Ye Han quickly took off his gravity pajamas, and his whole body immediately relaxed a lot.
The gravity on the moon is too low, and astronauts who are new to the moon will exert too much force if they are not careful. Even if they make an ordinary movement, they will fall out due to excessive force.
Moreover, the microgravity environment brings not only the problem of adaptability, but astronauts may also suffer from space sickness due to low gravity!
Human bones and muscles have evolved to resist the gravity of the earth, and the state of weightlessness will cause the degeneration of bones and muscles. When an astronaut stays in space for a month, the amount of bone loss is between 1% and 2%.
Muscle loss is even more severe, with an average loss of five percent per week.
The moon's microgravity environment will also cause the same situation, but the loss rate will be slightly slower.
If things continue like this, all astronauts will never return to Earth in the future. Even if they do go back reluctantly, they will end up with a second-class disability.
But it’s not impossible. Astronauts on the space station use exercise methods to reduce bone and muscle loss. The method used on the moon base is to wear gravity suits!
This thing was designed on the ground for lunar astronauts. Its function is to increase the weight of the astronauts, so that the weight of the lunar astronauts' bodies is the same as that on the earth, so as to avoid the loss of bones and muscles.
